摘要：

The packed-bed plasma reactor was energized by bipolar pulse power in this paper. In order to optimize the structural and electrical parameters of the packed bed plasma reactor, we investigated the effects of the shape of discharge electrode, diameter of discharge electrode, inner diameter of the outer quartz tube, diameter of the packing materials(glass beads), pulse-forming capacitance and pulse repetitive frequency on the discharge power. It was found that the bolt electrode showed better discharging characteristics than rod electrode. Larger discharge electrode diameter, smaller inner diameter of both the outer quartz tube and packed glass beads could contribute to the increase of injected energy to the plasma reactor. With the same applied voltage, when the pulse forming capacitance increased from 0.5 to 1.5 nF, both injected power and peak current increased dramatically. However, when the forming capacitance was over 1.5 nF, the injected power and peak current had little variation. Therefore, the optimal pulse forming capacitance was 1.5 nF in this experiment, which was 20 times of the statistic capacitance (75 pF) of the packed-bed plasma reactor. © 2016, High Voltage Engineering Editorial Department of CEPRI.
